That, and the conductor sizing algorithm in general. It may seem like it is a question of just a few conductors, but it is a question that propagates across an entire project.
I was under the illusion that a continuous rated device is the same "gizmo" as the equivalent standard rated device that had been re-labelled with a different rating. And I wanted to understand if/how it really was any different.
My understanding has always been that it is all about terminal temperature - the 80% rated device needs larger conductor because the conductor is a heat sink for the breaker the 100% device though it may sink some heat into conductor is not as much as the standard breaker.
